Abstract

The utility model relates to a chain type road barricade. A step-shaped hole is arranged in a dummy club on the upper surface of a chain plate, both ends of each chain plate are respectively provided with a cylindrical pin hole, and both ends of a chain plate in the middle part are respectively hinged into chain type structure with one end of a front chain plate and one end of a back chain plate. The upper part of a conical pin is cone with a plurality of edge blades, and the lower part is a cylinder. Grooves between every two edge blades are provided with small through holes and are communicated with a central hole of the cone. The cylinder of the conical pin is inserted into the holes of the dummy clubs of the chain plates and is fixed by an annular circlip. The utility model can be quickly pulled to be arranged on the road surface to form the barricade, the inner tubes and the outer tubes of a vehicle are stuck, the vehicle is intercepted, and the suspect can be caught. The utility model is also convenient to roll and clear the barricade, and can be popularized and used for the departments, such as public security departments, armed police departments, traffic departments, etc.

Description

A kind of chain type roadblock

The utility model relates to and is used to force the device that fastens vehicle or make its paralysis, particularly a kind of chain type roadblock.

Departments such as public security, People's Armed Police, traffic drive or when stealing car suspect, roadblock will be set all generally promptly arresting, and roadblock is generally used forms such as automobile, stone, trees, wire gauze.Can this type of roadblock often be subjected to road width and in time collect condition restriction such as above-mentioned goods and materials, time-consuming when being provided with or remove, and easily affects adversely opportunity.

The purpose of this utility model is to design a kind of chain type roadblock easy to use.

In order to achieve the above object, the technical solution adopted in the utility model is: it comprises carrier bar, the awl nail, straight pin, annular spring, have stepped bore in each boss above the piece carrier bar, the carrier bar two ends have cylinder pin hole, one end of a middle carrier bar and an end of last block of carrier bar are hinged with straight pin, the other end of a middle carrier bar and an end of a back carrier bar are hinged with straight pin, the rest may be inferred constitutes chain structure, the top of awl nail is the cone body of multi-edge blade of triangular or four ribs or many ribs, the bottom is a cylinder, all have small through hole in the groove of two edge blade spaces and be communicated with the centre bore of awl nail, form matched in clearance in the boss hole above the cylinder insertion carrier bar of awl nail, be stuck in annular spring and will bore nail in the cannelure of cylinder lower end of awl nail and fix, the vertex of a cone maximum spacing of two adjacent cone body of multi-edge blade can not be greater than the tyre width of motorcycle.

The utility model has the advantages that: it can be assembled into random length as required, can draw back fast when not only using to be arranged on and form roadblock on the road surface, poke the car Tire ﹠ Tube, interception suspect vehicle, simultaneously also can roll the removing roadblock apace, concerning departments such as public security, People's Armed Police, traffic, can promote the use of.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is that the awl nail is the structural representation of four rib sword cones;

Fig. 4 is the structural representation of carrier bar;

Fig. 5 is the structural representation of another kind of chain;

Fig. 6 is the structural representation of another kind of carrier bar.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, have stepped bore 12,13 in each boss above the piece carrier bar, the carrier bar two ends have cylinder pin hole, one end of a middle carrier bar 3 and an end of last block of carrier bar 1 below it are hinged with straight pin 2, the other end of a middle carrier bar 3 and an end of the back carrier bar 7 above it are hinged with straight pin 2, and the rest may be inferred constitutes chain structure.The top of awl nail 5,6 is four rib sword cones, the bottom is a cylinder 10, all have small through hole 8 in the groove of two edge blade spaces and be communicated with the centre bore 9 of awl nail, bore in the boss hole 12,13 above the cylinder 10 insertion carrier bars of following closely and form matched in clearance, be stuck in annular spring 4 will bore in the cannelure 11 of boring the cylinder lower end of following closely to follow closely and fix.

As Fig. 3, Fig. 5, shown in Figure 6, have stepped bore 12,13 in each boss above the piece carrier bar, the carrier bar two ends have cylinder pin hole, the groove 17 of one end of a middle carrier bar 15 is embedded in an end inserted sheet of last block of carrier bar 14, hinged with straight pin 2, the other end inserted sheet 18 of a middle carrier bar 15 inserts in the groove of next piece carrier bar 16, and is hinged with straight pin 2, and the rest may be inferred constitutes chain structure.The top of awl nail 5,6 is four rib sword cones, the bottom is a cylinder 10, all have small through hole 8 in the groove of two edge blade spaces and be communicated with the centre bore 9 of awl nail, bore in the boss hole 12,13 above the cylinder 10 insertion carrier bars of following closely and form matched in clearance, be stuck in annular spring 4 will bore in the cannelure 11 of boring the cylinder lower end of following closely to follow closely and fix.

The awl portion of nailing on of each carrier bar is same shape cone body of multi-edge blade, and the utility model adopts four rib sword cones; Or the awl portion of nailing on of each carrier bar is the difformity cone body of multi-edge blade, as adopting the combination or the more combination of cone body of multi-edge blade of triangular sword cone and four rib sword cones.

This chain type roadblock can be formed the length of needs, be arranged on fast on the road surface of any situation with one or several, the pressure wheel of (automobile or motorcycle) is when this roadblock in case suspect drives, when the awl nail protrudes into vehicle tyre and gos deep into to the carrier bar board plane, because the diameter of cone body of multi-edge blade bottom surface is greater than the boss diameter of carrier bar, when wheel leaves, the effect of wheel rubber tension, annular spring comes off, the awl nail is tightly wrapped on tire, and the centre bore that Compressed Gas is directly bored nail by the groove small through hole of two edge blade spaces in the tire is discharged from, and car is difficult to travel, be convenient to interception car, arrest suspect.

The vertex of a cone maximum spacing A of above-described two adjacent cone body of multi-edge blade can not be greater than the tyre width of motorcycle, its objective is to guarantee that motorcycle tyre also can poke.
